The following may help.  Since it involves editing the registry, the normal
caveats apply (back up your system, etc.).  Depending on how MIS set up your
system, you may have to get Administrator privileges on the local machine.
I've used the following procedure on SP5.  SP6a "should not" be any
different.

1.  Choose Run from the Start menu, enter 'regedt32' and click OK.
2.  Select the window labeled "HKEY_LOCAL_MACHINE".
3.  Scroll down to the folder icon labeled "SOFTWARE" and double-click to
expand.
4.  Scroll down to the folder icon labeled "Classes" and double-click to
expand.
5.  Scroll down to the folder icon labeled ".hgl" and select it.
6.  Hit the Del key.  Click 'Yes' on the confirmation message box.

You might want to try out some of the public Microsoft newsgroups for future
NT problems.
